The fertilized egg needs to go through a series of growth and development before slowly forming a gestational sac, so fetal growth requires a certain amount of time, and the development situation at each stage is also different. As the gestational age increases, pregnant women can go to the hospital to observe the fetal heart and fetal buds, which is a sign of good embryonic development and can also reassure pregnant women. However, how many days can the fetal heart and fetal buds be seen on ultrasound?
Ultrasound can show fetal heart and fetal sprouts at 60 days, and the formation time of fetal sprouts will be earlier than that of fetal heart. Therefore, if you want to see both, you can go to the hospital for examination around 60 days of pregnancy. If no fetal heart or sprouts are found during the examination, there is no need to worry excessively. It is recommended to wait for about one or two weeks before going for a follow-up examination.
The time when a pregnant woman develops fetal heart and fetal buds is not necessarily the same, as it can be influenced by many factors. For example, if the fertilized egg implants late, the fetal heart and fetal buds may not appear as quickly. As long as they can form smoothly before 8 weeks of pregnancy, it is sufficient. If there are still no fetal heart and fetal buds after 8 weeks, other tests should be combined to determine whether fetal arrest has occurred.
At the beginning of hearing fetal heart rate, it feels very weak and requires high-precision instruments to be heard. It can only be heard with a regular stethoscope after 17-18 weeks of pregnancy. In addition, monitoring fetal heart rate is influenced by many factors, such as different fetal positions or excessive fat in pregnant women, which can affect the hearing of fetal heart rate.
